The display shows that American movies appear to be bimodal, with a typical running time of around 95 minutes and another peak around 125 minutes. On the other hand, French movies are unimodal and strongly positively skewed with a typical running time of around 95 minutes. This suggests that French movies tend to have a shorter running time compared to American movies, but with a larger range of running times compared to the peak of American movies around 95 minutes.

in a study, the sample is chosen by using the random number generator on your ti-83 to generate a number, like 3, then taking every 3rd person in the list
Systematic sampling involves selecting every nth item from a list, potentially with bias and non-random results, so choose carefully.
The method used to choose the sample in this study is called "systematic sampling". This involves selecting a starting point (in this case using a random number generator) and then selecting every nth item (in this case, every 3rd person) from a list to form the sample. This type of sampling can introduce biases in the sample if the list has some pattern or structure, so it's important to be aware of these potential issues when using this method.
In systematic sampling, the selection of each member of the sample is based on a fixed and systematic rule. The advantage of this method is that it is easy to implement and cost-effective. The disadvantage is that if the list has any pattern or structure, such as alternation or clustering, the sample may not be representative of the population. It's important to carefully consider the list and choose an appropriate starting point and interval to reduce the potential for bias.
It's also worth noting that systematic sampling may not result in a random sample, as the sample members may not be independent of each other. This can have implications for the validity of inferences made from the sample to the population. Therefore, it's important to carefully consider the properties of the population and the goals of the study when choosing a sampling method.

X, Y are two independent N(0,1) random variables, and we have random variables P,Q defined as P = 3X + XY 2
Q=X then calculate the variance V ar(P + Q)
The variance of P + Q or Var(P + Q) for given random variables is 14.
Since X and Y are independent N(0,1) random variables, we have Variance of X = 1 and Variance of Y = 1.
Given, P = 3X + XY
Variance of P = Variance of 3X + Variance of XY
= 9 + Variance of X * Variance of Y + 2 * Covariance(X,Y)
= 9 + 1 * 1 + 2 * Covariance(X,Y)
= 10
Given, Q = 2X
Variance of Q = Variance of 2X
= 4 * Variance of X

g is group of order n and f is given by action of g on g via translation. what are the number and lengths of disjoint cycles of f(a)
The number and lengths of disjoint cycles of the function f(a) (where f is given by the action of a group g of order n on itself via translation) depend on the specific group and the specific element a being acted upon.
If g is a finite group, then the function f(a) has precisely n disjoint cycles, each of length a power of a prime dividing n. The factorization of n into primes determines the number of cycles of each length.
If n is a prime number, then g is a cyclic group and f(a) has precisely one cycle of length n.
If n is a composite number, then f(a) will have distinct length cycles.
The cycle lengths correspond to the divisors of n, and the number of cycles of each length corresponds to the number of times that divisor appears in the factorization of n.
In any case, to determine the specific number and lengths of disjoint cycles of f(a), one would need to know the specific group g and the specific element a being acted upon.

if the scores are ordered ascending, center is the center score:
95, 110 , 118, 118, 122 , 125, 126, 130, 139, 141
Median = 118
c. Standard Deviation:
The standard deviation indicates how spread out the information is. Here's a recipe for finding the standard deviation:
Standard Deviation = sqrt(Variance)
d. Variation:
Variation is the proportion of variation in the set of information. The recipe for determining the change is:
Variance = (amount of ((each score - average)^2)/(number of scores - 1)
connect the numbers obtained:
Variance = (( ( amount of each score - ) 121.4)^2)/(10 - 1)
Variance = 1579.
24/9 = 175.47
standard deviation = sqrt(variance) = sqrt(175.47) = 13.21
e. minimum:

Step 1: Write the first function substituting x for 4: f(6) = 6 + 5.
Step 2: Solve the function: f(6) = 6 + 5 = 11.
Step 3: Write the final answer for the first function: f(6) = 11.
Step 4: Write the second function substituting x for 4: g(4) = 3 x 6 + 10.
Step 5: Solve the function: g(4) = 3 x 6 = 18, and 18 + 10 = 28.
Write the final answer for the second function: g(4) = 28.
Step 6: Add the output answers together: 11 + 28 = 39.
Step 7: Write the final output answer for both functions: (f + g)(4) = 39.
Part C: 39 represents the total number of animals adopted at two shelters in 6 months.
someone please help me with this i suck at math and im losing my mind right now thank you.
The factors of the cubic function f(x) = 27x³ + 8 are ( 3x + 2) and ( 9x² - 6x + 4 ).
What are the factors of the cubic function?Given the function in the question;
f(x) = 27x³ + 8
To determine the factors, first rewrite 27x³ as (3x)² and 8 as 2³
27x³ + 8
(3x)² + 2³
Since both terms are perfect cubes, factor using the sum of cubes formula.
a³ + b³ = (a+b)(a² - ab + b² )
Here, a = 3x and b = 2
Plug in these values
(a+b)(a² - ab + b² )
( 3x + 2)( (3x)² - (3x)×2 + 2² )
Simplify
( 3x + 2)( (3x × 3x) - (3x)×2 + 2² )
( 3x + 2)( 9x² - 6x + 4 )
Therefore, the factors are ( 3x + 2) and ( 9x² - 6x + 4 ).

On the planet Gespil, there are 5 frophs to every 12 umpts. If farmer Pisquet has 50 umpts on her joogh farm, how many frophs are on the farm?
The number of frophs on the farm is 21 frophs.
How to find the number of frophs on the farmFirst we need to determine the ratio of frophs to umpts and then multiply that ratio by the number of umpts on the farm.
The ratio of frophs to umpts is 5 frophs per 12 umpts, which can be simplified to 5/12 frophs per umpt.
If farmer Pisquet has 50 umpts on her joogh farm, then the number of frophs on the farm is:
50 umpts * (5/12 frophs per umpt) = 20.83 frophs
Rounding to the nearest whole number, the number of frophs on the farm is 21 frophs.

there are 35 rides at a large theme park. a team of journalists wants to interview some customers to get their opinion on the best rides in the park. the journalists randomly choose 5 of the rides and interview all of the people exiting those rides.
The correct option Cluster random sample.
In cluster random sampling, at first the population is divided into several small non-overlapping sub-populations and these sub-populations are called clusters.
The size of the cluster may or may not be equal.
Units within the cluster should be as heterogeneous as possible, i.e. one cluster could represent the population, and units between the clusters should be homogeneous.
Then simple random sampling is used to select some sample cluster and all the units of the selected cluster are taken as sample units.
Cluster sampling can be more cost-effective than simple random sampling, especially if the population is dispersed across a large geographical area.
However, cluster sampling methods tend to be less efficient than either simple random sampling methods or stratified sampling methods and often require a larger sample size.
The entire population: here all customers are divided into several clusters: here 35 rides. Sample of clusters: here 5 rides are selected and all items in the selected 5 clusters are included in the sample.
Therefore, the correct option is Cluster random sample.

triangle abc and trianglee xyz are similar triangles. the lengths of tow sides of each triangle are show. find the length of the third side of each triangle
The length of the third side of ΔXYZ is 6 meters and the length of the third side of ΔABC is 11 meters.
ΔABC is similar to ΔXYZ
So, The sides of the two triangles are proportional to each other.
AB/XY = 6/3 = 2
BC/YZ = 11/5.5 = 2
To find the lengths of the third sides:
For XZ, we can use the proportion of AB/XY to find XZ. Since AB/XY = 2, we have XZ = 3 * 2 = 6.For AC, we can use the proportion of BC/YZ to find AC. Since BC/YZ = 2, we have AC = 5.5 * 2 = 11.So, the length of the third side of ΔXYZ is 6 meters and the length of the third side of ΔABC is 11 meters.
